I think so long as you're provinding a suitably humid environment (maybe a little more humid than usual for these questionable ones) and they each have a waterbowl they can soak in if they choose...it may be a matter of letting nature take its course. Their little bodies may need time to recover from the stress of their journies and whatever neglect they may have suffered along the way that you can't know about.

Top-notch husbandry, good food, and as little stress as possible should hopefully set them to rights, but it may take a few weeks.
